1. 1. How do fires affect the railway? - A Swedish study on what factors influence fire risk and how it affects railway traffic.

   Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och väg

   Författare :Jonatan Gustafsson; [2023]
   Nyckelord :Train; railway; fire; forest fires; delays; weather; Sweden.; Technology and Engineering;

   Sammanfattning : Forest fires can start in a variety of ways. "Fires started deliberately" and "fires started by sparks generated from a train braking" were two of the most common causes of fires between 2010 and 2020. Train braking accounted for 1.1% of all fires, whereas fires created by unknown reasons accounted for 43% of all fires. LÄS MER

3. 2. Linearization Based Model Predictive Control of a Diesel Engine with Exhaust Gas Recirculation and Variable-Geometry Turbocharger

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Jonatan Gustafsson; [2021]
   Nyckelord :MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

   Sammanfattning : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. LÄS MER

4. 3. Yxa, grav och människa. : En studie om vapensymbolik och yxans roll i gravskicket på Birka.

   Kandidat-uppsats, Uppsala universitet/Arkeologi

   Författare :Jonatan Gustafsson; [2021]
   Nyckelord :Axe; burial practice; grave goods; Viking age; weapons; symbolism.; Yxa; gravskick; gravgods; Birka; vikingatid; vapen; symbolik.;

   Sammanfattning : The purpose of this thesis is to study the symbolic role of weapons, specifically axes in Viking age burials. The thesis will also discuss the axe´s role in relaion to the character of the grave and the grave goods. A total 18 graves will be studied and analysed with help from J. LÄS MER

5. 4. Investigation of generative adversarial network training : The effect of hyperparameters on training time and stability

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

   Författare :Alexander Gustafsson; Jonatan Linberg; [2021]
   Nyckelord :Generative adversarial networks; hyperparameters; training; neural networks; deep learning; EMNIST;

   Sammanfattning : Generative Adversarial Networks (GAN) is a technique used to learn the distribution of some dataset in order to generate similar data. GAN models are notoriously difficult to train, which has caused limited deployment in the industry. The results of this study can be used to accelerate the process of making GANs production ready.

7. 5. Reverse Logistics Management in Construction : A multiple case study examining the effect of organisational size

   Master-uppsats, Jönköping University/Internationella Handelshögskolan

   Författare :Jonatan Gustafsson; Linnea Bengtsson; [2020]
   Nyckelord :Reverse logistics; construction management; organisational size; re-used material; waste management;

   Sammanfattning : Background: Increasing awareness for the environmental impact, governments and higher authorities has in the past years issued regulations for waste creation and management, creating a need for new practices and policies on how used material is handled. Reversed logistics could simply be described as the process of ensuring value creation spanning over the entire life cycle. LÄS MER
